I'm tall and thin and growing up, I envied my fat friends for having meats. And these same fat friends got dates in school, while the slimmer and taller one went date-less.
Till today, I don't understand what's the problem being with fat? I mean obese - yes that's extreme, but a little extra meat and curves are totally fine by me.
Fat is a physical descriptor.
It is very closely associated with Ugly.
These are very baseline negative-descriptors.
So when we envoke these terms, an entire cascade of associated definitions cross our minds.
In that way, it's a very powerful and loaded term..
This is extra damning to younger people.
An adult has a car, a house, a wife, a job, a salary, a keyboard collection.. Who cares what people think.. He's got everything he needs.
A young person has none of those things. He is fundamentally his body and whatever resource his parents allot him..
When a young person enters the school environment, Outward beauty is the only currency in the absence of Actual state-currency..
In that way, we can view the young persons social ladder with Ugly or Fatter population equivalent of destitute or homeless, while the beautiful people are the billionaires.
When we build these very basic file folder names from youth, FAT may end up being the launch icon for all of one's life's inadequacies and failures, etc
-- not getting females
-- not getting males
-- not getting picked
-- getting picked on
-- embarrasement
-- teasing/ bullying..
So that's why FAT is so terribly Terrible..
